Abstract:

A roller synchronization detecting system based on virtual instrument technology is proposed to detect the speed synchronization of rollers of a drawing frame. The system is composted of DAQ cards, PCs and roller speed curve testers. The speed calculation method based on M/T is proposed and the roller speed tester is designed in LabVIEW environment. The detection system bas been successfully used on detecting performance of the drawing frame FA1382. The results show that the detection system can acquire accurate data and data is highly versatile and intuitive. Data analysis show that the drawing frame has good draft performance, but it has also some aspects to be further improved such as nonlinear speed down in normal stop and time control of slowdown in emergency stop. This detection system provides more effective quantitative reference data for judging the performance of drawing frame and improving drawing frame.
